They typically contain between 20 and 50 emitters each being e g.
Laser diode bars.
Wavelengths include 780 830nm 880nm 915 980nm 1060nm and 1400 1500nm.
Diode bars are high power semiconductor lasers laser diodes containing a one dimensional array of broad area emitters or alternatively of subarrays containing 10 20 narrow stripes.
The number the width and the spacing of the emitters are dependent on the manufacturer.
Ceos laser diode bars are offered on over 200 packages designs with multiple wavelength options available.
Coherent unmounted bars have set the standard for high reliability in real world applications.
And coherent continues to push forward with ongoing advances in power brightness efficiency and divergence.
The relative value of the emitting areas in the active layer with respect to the bar width is called filling factor ff.
High power diode laser bars for pumping and direct diode applications.
